All three are scrolls of some sort of forced sending spell, like Teleport, but with unwilling targets, and not self-targeting. The spell is one you've never seen before, and would require a more complex grasp of arcane energy than you currently possess, but you can understand it vaguely, and could probably copy it into your spellbook for later. (You could copy it into your spellbook, but you can't cast the spell yet, since it's a level 5 conjuration.)
