Ioc'thual, the ancient shard beast

This monstrosity is truly a jaw-dropping sight. It is gargantuan in size

and yet looks humanoid, but every inch of it is shielded by a crystalline
like skin, which is seemingly impenetrable. It has been rumoured that the
powerful shards which can be occasionally found can have the ability to
corrupt ones body if exessively fiddled with. This humanoid creature is
perhaps the maker of this temple, corrupted by the powers residing within
the shards and now it only lives to find and consume as many shards as
possible. It has been lured here by the sheer magical aura of the shards
laid upon the altar. It moves sluggishly, but then again what does it has
to fear in this realm or another?
