The engine sometimes acts a creature, with baldur.bcs as its script. Imp has mentioned this once, but he was probably just talking. It can refer to itself as Myself and then DisplayString(Myself,123), which works as a non-attributed DisplayString. This is what the area file for Ulgoth's Beard begins with.

The engine can also ReallyForceSpellRES directly, without having to go through ActionOverride of a creature. I mean, we all know the engine can do ApplySpellRES, but that works differently: the projectile hits the target instantly, and if it is an area-of-effect power, only the hit target is affected, there is no trap and no visual. So ApplySpellRES("SPWI001",Player1) with my favorite spell in the game just kills the Player, standing in the group, and even without any signs of fire.
