As Muzdim and Myst move towards the retreating creatures, they continue to race along the walls apparently as fast as they can, easily outpacing the two clerics. And they stay on their respective walls as they reach the Y shaped intersection at the western end of the tunnel that the party finds themselves in. The one with the glint on its finger darts into the left (southwest) tunnel, while the other moves into the (northeast) tunnel. The latter pauses for a moment to look back, and bares its wide jaw into another hiss before vanishing from sight.
Stellan pauses, realizing that some of the party doesn't appear to be moving with Myst and Muzdim, and that they're torchless, so he stands near Antares and Bosco, but still watching down the tunnel that Myst and Muzdim are walking along. His light extends to give the halfling and the elf some illumination.
The coins are slightly acid scarred, but reasonably legible: a dozen gold pieces of the variety used in Ascadar. The skeleton, on somewhat closer inspection appears to be almost completely whole - and while the flesh and clothes have been eaten completely away, there's very little damage or pitting to the bones themselves except for the change of their color from gleaming white to a dullish grey.
The axes thrown by Muzdin do lie in the eastern portion of the corridor, but beyond that - where the Gelatinous Cube had originally been, other things 'glint'.
