Question is pretty much in the title. A player wants to play Polis Massan and we couldn't find how old they get...

Does he watch his cholesterol intake and jog?

I searched the books and Wookieepedia about any age ranges for the Kallidahin; I found nothing.

In this gap, may I offer a suggestion about this highly adaptive species? Let them transfer their consciousness into a droid at such point a player feels their character is too aged. As a species, they have great cloning skills and medicine, which may suggest a younger clone to replace the old character, too. While not a perfect solution to your inquiry, I think these ideas offers fun play. I'd allow a player to use these tactics for a relatively benign species with no significant influences in the galaxy aside from medicine and/or cloning.

Unless it says otherwise assume human lifespan.

It's lazy but tends to be ture.

How long do your campaigns last???

I'm not sure my campaigns have anything to do with the recommendations of consciousness transfers as suggested. Honestly, an aged Polis Massan going on a (silent?) quest to do just this work may easily match how an aspiring Force-User wants to build a lightsaber.

Given the proliferation of droids, droid parts, and sci-fi medicine, I contend it'll be 1000 times easier to do what I suggested than build a lightsaber and use it without hardship...but players stand in lines to play wanna-be Jedi (despite being told that there are no Jedi remaining post Order 66).

I offered a work-around, regardless of campaign length. The PC may do set out to do it from Day One (and thus play an aging Polis Massan), or it can be a long-term goal by which a non-aged Piolis Massan begins to postulate these ideas and seeks out other examples across the galaxy.

Or, just say they live, like, I dunno, 100 years without accident/injury/illness/etc. and bake a vanilla cake.

Whose characters are dying from old age? When has this ever come up? Ever?!

I understood the OP's question but then it escalated so quickly from there! I have never seen such weird assumptions and leaps of logic that I just can't right now...

Not that I am not enjoying reading this!

I drew my assumptions from reading canonical history of this species. They like medicine. They save lives. They build stuff. They have ties to cloning. When someone wants to know how old they are, I considered these things and offered that age may not mean anything to this species because of their options in any of the above examples.

I believe the alien book for D20 Star Wars had age ranges for each species. Not sure if these aliens were included in that though.

No, and I am really not trying to be an ahole here, you answered a question of "how old do they get?" with "If they get too old have them become a droid". Which is why I started asking whose characters ever "get too old"...

Again, I am not being mean I just thought it was a funny escalation of the question.

My reasoning: there is no definitive canonical data about this species' lifespan. I anticipated how age may be a factor in the game, and wanted to show creative ways around age, given what we already know about the species.

I could have been a jerk and just said, "No data, deal with it."

I could have incorrectly guessed any number from 0-900.

I could have lied and said "...page 100 from an old WEG book that I'm certain is out of print, but trust me when I say they live to X standard years."

I could have derailed this thread without offering any advice myself and instead take exemption to something someone else wrote that I don't understand, and feign not being a turtle-headed pantywaste for my veiled animosity about how useful said answer might be to the OP.

I chose creativity and honesty about data.

Yeah, it did. But I still don't understand how and/or why we got here.

I also went out of my way to point out that I was not being mean spirited about it and was just baffled but amused at the same time. But I guess trying to figure out what is going on and why equals me to "pantywaste" and apparently I am hiding my animosity (which I really don't have.)
