Ok, I hope this post doesn't magically double...
Have you created a chapter for DW? If so, share it with us.
My chapter is called "the Force of Wisdom". I came up with it for two reasons...
One, there were notes that if a chapter suffered a loss of it's black carapace or progenoid implants itn would be the end of the chapter. This made me wonder how a chapter might survive a flaw that affected these.
two, I really liked the mentor legion but never could stand the green and white power armor colors. The owl symbol was a nice tough but in reality owls are not very bright birds regardless of appearance, and in truth the most intelligent bird in the raven and it's cousin, the crow. (I had a memorable experience with 3 crows one, if anyone's interested I'll tell you.)
So I had a few ideas that merged together in a mental petri dish in my mind and produced a new marine chapter.
The Force of Wisdom is a fairly unique, non codex chapter that was based on the ravenguard chapter. Shortly after their founding a disaster struck them when failures develiped in their geneseed that resulted in frequent failures of their black carapace and progenoid implants. In about half the cases of a Force of Wisdom inductee, the black carapace fails to form correctly and atr least one progenoid does not develop.
While many others may have seen these as omens of doom, the force of reason chapter refused to simply collapse and instead adapted to their circumstances. Fully half the chapter cannot use power armor, so they wear scout armor thru their careers that has usually been adapted to serve in more environments than the usual. There are variants that can keep a man alive and fighting ijn vacuum, under water, in polluted and or radioactive environments, etc.
The FoW can field these units as full battle squads but more often relies on them as a massive reconnaissance force.
Also, the FoW frequently works had in gauntlet with the Imperial guard, adeptas soriatas, frateris milita and other imperial fighting forces to bolster and augment imperial forces rather than doing the brunt of the fighting. Due to their low rate of progenoid production, they are particularly loathe to lose battle brothers, but never hesitate to do so when necessary, They frequently work to make conventional imperial for4ces more effective, however. FoW scout squads are remarkably effective at gathering and delivering intelligence, thanks to various factors such as vast experience with scout armor and unusual amounts of advanced equipment. FoW scouts seem to have access to large amount of cameoline, fore example, and many of them enhance their senses with advanced wargear such as hi resolution long range man portable auspex devices and cybernetic enhancement of their senses. The fact that the FoW has access to these items suggests a strong tie to the tech priests of the Adeptus mechanicus, a situation neither side denies or confirms.
The information the FoW relays, often in near real time, has drastically increased the eff4ectiveness of conventional imperial forces they are assisting. Plus precision, calculated strikes against key enemy targets by scout units and the chapters conventional battle brothers have an effect vastly our of proportion to their actual numbers or physical damage done.
It is rumored that the FoW sometimes enhances the effectiveness of imperial force commanders they work with thru close 'advise and counsel" that may involve using modified hypno conditioning and teaching equipment normally reserved for adapetus astartes forces. These sessions of hyypno therapy conditioning are rumored to quickly increase the skill levels of commanders subjected to them, at least for a limited time.
While an unconventional marine chapter the effectiveness sof the FoW has been inarguable, and plain to see for all who have access to the full data set. Some marine chapters have disdained and even scorned the FoW for not being as quick to send mass formations into heavy combat, the FoW simply keeps its own council on such accusations.
The ultimate sanction of the FoW's methods came when the high lords decided to model anew chapter of marines upon their dogma, if not their geneseed, and call it the Mentor Legion.
The chapter's legendary reputation for levelheadedness, clarity of thought and precision of action in addition to their economic use of force has seemingly endeared them to both the Adeptus mechanicus, who seem to work closely with them on many occasions and favor their aid over more conventional chapters when necessary, and to the Inquisition who often needs a more precise, stealthy instrument of force than many chapters can provide. it is rare but not unheard of for a kill team to be composed mostly or solely of FoW brothers.
The FoW seems to benefit from their strong connections to the AM and inquisition, as they seem to have a larger amount of heavy combat vehicles, dreadnoughts and other "force multipliers" than most chapters in addition to the previously mentioned amounts of advanced gear they seem to have access to, and it is not uncommon for FoW scout squads to seemingly have access to small amounts of gear normally reserved for Killteam marines.
it is thought the FoW occasionally receives shipments of fresh geneseed cultivated from the raven guard chapter, to help maintain their numbers. Also, initiates who have failed to become full marines in some cases are allowed to live and mature serving in various roles after being implanted with progenoids, which are harvested upon maturity. It is possible to harvest progenoids from a live carrier tho difficult and time consuming, and the subject does not always survive, yet due to their shortage of progenoids the FoW does taken this risk frequently rather than risk loss of their limited supply of progenoids on the battlefield.
The chapter symbol is an open book, a vast tome, in front of a vertical sword, point down. A large raven sits upon the pommel of the sword. The chapter colors are the color of writing, black and white, and their creed it "Wisdom without force is powerless. Force without wisdom is chaos. We are the force that gives wisdom power. We are the Wisdom that gives force purpose."
