Yeah. Most of them were published after the Eberron Player's Guide (a good-sized chunk came from that Dragon article with a bunch of new rituals). Only the ones with a * are available to pick up for free, though...Holy cow, that's a lot!
Well, Shadow Walk is of at least some use there, and House Orien and House Lyrandar are perfectly willing to sell their services...Of course, the ones I had my eye on were the travel rituals. The portals and so on. But perhaps we don't need those right away...
