When my players created their ship today they rolled 10 on the table for the ships past with the result Xenophilos. Because of the xeno parts integrated in the ships engineering all Repair Tests on the ship have -30 modification. We choosed to interpret this that some of the ships part are partly alien (not just the xeno component).
The players choose the eldar Runecaster as their xeno component and therefore the ship has been partly modified with eldar technology in the past. Because of this some of the ship has an alien eldar design on its architecture.
So how does eldar ships internal architecture look like?
Some ideas that came up was mosaic walls of colored crystals with mirror like effects. Do you have some more ideas of what the eldars design can look like?
Happy for answers...
