He initially adopted the persona in the 2010 Christmas event to try and spread Christmas cheer to the Fremennik of Daemonheim. According to Thorvar, Thok did not dispute him being a Fremennik, claiming he was obviously a Fremennik as "he climbs through chimneys and into fireplaces, he is almost as strong as me".
During the duration of the 2014 Christmas event, Thorvar was located at the lodestones in most major towns accepting Bonds as donations for Oxfam. The rewards for this are the Oxfam present, 'the Festive' title and the Oxfam Reindeer Antlers. After the first of January he no longer accepted Bonds, and he was removed once again on 5 January. Interestingly, Santa could be also found in his normal attire at the Lumbridge Crater at the same time.
