Zarnok, a seasoned Troglodyte cleric, has lived for over two centuries, his age marked by the deep creases that run across his scaly, greenish-blue skin. His eyes, a piercing yellow, reflect a wisdom and resilience borne from a life of spiritual devotion and battle. Standing tall and muscular, Zarnok's presence is both intimidating and comforting to those who follow the path of the divine. His attire is a blend of practicality and reverence: a dark, sturdy robe adorned with symbols of his faith, complemented by a unique weapon - a reverse glaive topped with a lantern that casts a soft, ethereal glow.

Zarnok's unique ability to bend water to heal himself and others is not only a testament to his clerical prowess but also to his deep connection with the elemental forces. This power stems from his belief in the sanctity of life and his dedication to preserving it, a conviction that guides his every action. Yet, despite his healing abilities, Zarnok faces a relentless struggle against the encroaching darkness that threatens his subterranean home. The darkness, both literal and metaphorical, seeks to snuff out the light he carries, both in his lantern and within his heart.

His journey is one of perseverance and faith. Zarnok seeks to restore balance and peace to his world, a world where the light of hope is dimming. The challenge lies in the overwhelming forces of chaos and destruction that seem to grow stronger with each passing day. Yet, Zarnok does not falter; he uses his healing powers not only to mend physical wounds but also to inspire and rally his people, teaching them resilience and the power of unity.

His efforts are met with success, not because of brute force, but through the strength of his spirit and the unwavering belief in the goodness of his cause. Zarnok's story ends on a note of cautious optimism, with the darkness pushed back, but never fully vanquished, a constant reminder of the eternal struggle between light and darkness.

Throughout his life, Zarnok faces numerous conflicts, from the external threats of darkness to the internal battles with doubt and despair. His unique trait is a soft, melodic humming that he does unconsciously when healing, a sound that brings comfort to those around him, a stark contrast to his otherwise stern demeanor.
