While Zarineth's personal identity has shifted over recent years, his commitment to the Lantern Bearers has remained unwavering.
Under the Winter Council
Unmasked and reformed
After the Winter Council's fall, Zarineth abandoned the identity of Swallowtail, revealed his true identity, and shed much of the organization's insular secrecy in favor of radical openness. He attempts to repair the Lantern Bearers' reputation as he also expands and reforms their scope to focus less on the eradication of the drow, and more on redeeming them and any other corrupted elves, as well as fighting the demonic incursions of Treerazer in the Tanglebriar.
