@ Moogie: I\'m aware of the fact that diseases are often carried by settlers. This, however, would have resulted in the disease spreading and being present since tzhe early days, or at least since the arrival of the last settler. However, this would still have changed Yliakums history at least sufficiently to warrant an entry in the player guide or the setting itself.
You
could of course argue \"Stone Labyrinth!\", but I\'m with Annah on this: I think that this very diseases don\'t belong / fit into the PS world. Not to insult you, but I believe to have read, in one of the many \"more races!\" threads, a post of yours which uses the very same argument that Annah presented here, and that I am also trying to make: embrace the PS history and immerse yourself in it, finding interesting and appealing ideas
within it, instead of trying to force concepts that you have seen in other games / stories onto PS, by trying to RP them. There certainly are foreign concepts that are woth adding, but the proposed one is well known, and as such to me the reason for it not being mentioned in / deductible from the setting is that it\'s deliberately been left out, i.e., not wanted.
It is my opinion that while there certainly is room and need for RPing things that aren\'t implemented, as you pointed out, but also that this room does have limits, which are the setting. Thus, it is possible to RP that your mother or even you work as scribe, because while this isn\'t mentioned in the setting it is reasonable to assume that this job exists, but not to RP a vamp, since there is no indication that this is intended in the setting.
In fact, it\'d be just like RPing a dragon. I also hate the idea of were-dragons, not just in PS, but in general, because were and dragon are opposed like fire and water IMO, due to the way I see dragons. It\'d be just like a were-philosopher, without the originality.

Anyway, back OT: what\'s a psychic vampire? One that sucks mana, not blood? That doesn\'t change anything, vamp is vamp. The very ability may be implemented or RP\'d as part of the conventional magic of Yliakum, but not vampiric in any way.
