I am not sure which spell I tried to cast which was overpowered when there was an empty slot.
But is was definitely not already an existing Global.

With regards to spells sticking around after the faction has disappeared: defintely a bug, not a feature. Spells should disappear after the caster has died, no?
And most of the time they do.

In this case I actually killed the relevant pretender before wiping out the faction. No luck though.
