I should probably clarify what the bestiary
IS, to give a better idea of what it
might be. For a long time now, the ShadowTaker has been, well...taking people. The Taken, essentially, are people he or his agents capture....and then he uses in one of two different ways:
- As dominated agents
- As meat-puppets
I mentioned before that he hadn't left his crypts PHYSICALLY for centuries....that doesn't mean he hasn't journeyed beyond their walls. He just doesn't use his own body to do it. The central part of the bestiary is...well, his 'body closet'.
Those who've followed the Story Hour will be familiar with the Tebhar'in ("those who cannot be wed"), better known as Zira bint Tebara and Zara bin Tebara. They are the exception to the rule of the closet, directly tied to the operation of the Pyre, which actually protected them and caused an unexpected result (which led to their freedom, though they don't actually know it).
The Shadow-Taker has perverted the power of the Pyre indirectly, by using it to create this 'body closet', which is essentially a 'bubble' demi-plane that is coterminous with the plane of positive energy. The bodies are stored there in stasis, until he calls for them, and imbues them with his persona, or dominates them and then sends them on a mission.
I fully expect the Bestiary to have holding pens for nasties, too, of course: nasties that are designed to be released when intruders come 'a callin'.
The Forge and the Furnace, I haven't developed, quite as much. I'm trying to avoid using fire and flame elements, as I've pretty much used them as much as I care to, what with Durance Vile, the plane of Fire, City of Brass and remaining Red Dragons. That's enough fire for anyone.
I'll have to read up on Spellfire in the FRCS. It's one of those things I've never actually paid much attention to, but this could definitely hold some possibilites, too. I really want to try and keep the players off of their guard, as much as possible. Every different Crypt should change the rules, so that they have to constantly adapt.
