Hœnir goes with Mímir to the Vanir as hostage, in order to seal a truce to the Æsir-Vanir war. During the negotiations, Hœnir heavily relies on Mímir to address any query, as the latter was better informed and knowledgeable. The Vanir perceived this indecision and thus noticing a character flaw within Hœnir, which resulted in beheading Mímir as retaliation, thinking the Æsir cheated them in their hostage exchange. Hœnir is one of the few gods to survive Ragnarök.
