Ethereal Travel

The Ethereal Travel spell is perhaps the most unusual of all of them.

It allows the caster to travel to the Ethereal Void, seeingly the only way to leave the world of Pagan. Where exactly into the void the caster teleports to however, is not determined and can be greatly influenced by outside forces. Also, the requirements for this spell are quite steep, as Blackrock is very difficult to find on Pagan, since it is very rare.

Note also, that unlike other spells, the "reagents" are not used up when charging the spellbook, meaning that the rare substance is not lost to the caster.

Generally, casting it on Pagan leads to the Ethereal Plane, the home of all four Titans, who won't allow anyone to escape their world in this way. That however also means that in that place, they are vulnerable.
