problems:
1. Recall only works for you. A portal would possibly allow others through
2. Recall is instantaneous (if not, it defeats the purpose of recall), so you'd never see the portal.
Now, a "remote viewing" type spell could be interesting, but not as part of mark/recall.
Yeah good point. Recall does need to be an instant thing. I still think it would be a sweet spell effect and I would love to see it done. Even if the spell is called a portal, which fits in perfectly in the TES universe if you ask me. It could be a high level spell you first see in the Mages guild but later pick up for yourself.
A remote viewing spell would be awesome. Especially for stealth based characters.
The portal portals would not be good.
Good to know. Care to elaborate sir?
