Glas Ghaibhleann

Deep within the twisted realm of Tir Na Nog, a massive beast is not born, but constructed. Bones of mana infused steel covered by thin, sallowed skin adorn the creature, its emaciated appearance deceptively hiding its horrifying strength. Long forgotten by those of the mortal realms, the tortured monstrosity awaits the call of its masters to reawaken it.

Ancient Siege Weapons. During the last reign of Cichol, Glas Ghaibhleanns were used heavily to not just break through the walls of cities, but to break the morale of those living inside. Easily standing almost fifteen feet tall when hunched over and over twenty feet tall when standing upright, Glas Ghaibhleanns are large enough to smash through most structures with ease and rip them apart with its four arms.

While appearing similar to the giants at a passing glance, the Glas Ghaibhleann is not of this world, and are summoned to it through an exhausting ritual that requires extensive construction of its massive skeleton. Only very experienced summoners have a chance of properly summoning this creature, and due to its feral nature, the skeleton must be heavily restrained prior to its summoning to prevent it from killing its summoners. In addition to the material requirements for its skeleton, the Glas Ghaibhleann consumes gold at a rapid pace, not needing air, food, or water due to its constructed nature.

Fickle Loyalty While the Glas Ghaibhleann can technically be summoned by any spellcaster with the proper experience and resources, the creature is never owned by the summoner. The creature is merely borrowed from Cichol, God of the Fomorians. Typically to complete the summoning, the caster must make a deal with the fickle deity, however due to the creature's nature it may still disobey if the caster goes back on their bargain or runs out of gold to feed its neverending hunger.
