Religion in PlaneShift is a reflection (as in, mirror reflection) of how religion works IRL. That's why you'll find a nutjob or two, and the rest will claim to follow Talad, Laanx, Xiosia, Dakkru... They're represented as much as certain expressions, rituals asking for protection, sporadic offerings, etc. Here are a few example I've seen in game, myself:
- By Talad, by Talad's/Laanx's beard, I swear to the Gods, Dakkru take you!, what in Dakkru's realm?, Xiosia's blessings...
- Before dueling, or a tournament, if it's not sparring but a honor duel, fighters will ask for strength to Talad, and for a good, honourable death to Dakkru.
- Different marriage ceremonies are made in the name of any one God, although most are blessed by Xiosia.
- There used to be many offerings at the Temple of Talad in Gugrontid. I myself have made some recently. These are meant to be taken, by either people in need, or the temple caretakers.
- Lovers will sometimes gather secretely in the Sacred Garden in East Hydlaa to get Xiosia's Blessing for their love.
There's a long etcetera. I wouldn't say religion is underrepresented, only unnoticed.
