You see movement behind the hulking creature.
It tries to move past the urn under the yellow lantern and bumps into it. The creature seems surprised the urn didn't just fall off its pedestal. It frowns, a bit like a gigantic infant would, and slaps it hard with the back of its hand. The blow is so hard you feel air displacement from where you're standing. The urn doesn't break, and doesn't even move. The creature slashed the back of its arm against the metal roof of the urn pretty bad. As its large elliptical movement ends high above the creature's tiny head you see some black blood spray all over the area to the north-earth of your position.
Just at the same time, you see smaller, humanoid creatures creep between the monster's legs and aside of it. These look like orcs, goblins, maybe hobgoblins. Hard to make out in the dark. There are at least five of them: three still behind the giant monster, two now stepping on the sickening goo by the urn. You see that the goo reacts to the creatures' steps. Tendrils of flesh, half-digested arms, skulls and guts of vomit caress their legs and provide them with support, even comfort as they walk towards you. They too seem to move in a slow, disjointed manner, like the huge giant-ogre thing, but also seem less absent-minded, their common attention definitely focused on you.
The basket reaches the ground. Othos and Ulas Xegg step out of it.
