Creature from the House of Darkness

An unknown creature has been discovered in the mysterious House of Darkness, concealed for ages inside a pyramid in the Sands of Time desert on planet Eternia.

Biology
This creature appears like a giant reptilian rat with sharp teeth, glossy black eyes, an armored hide, a long tail and a pair of curved spikes on its shoulders.

It's not known what this beast feeds on and how it remained alive for so long after the sealing of the House of Darkness; although given the circumstances, it might be a magically-created guardian of the place, which would explain its hostility towards intruders.
