So, as we all know, after they deposition and the fourth crusade, the Komnenian dynasty ended up ruling in Trebizond. With a POD after the sack of Constantinople (or the deposition of Alexios III if you prefer), would it be possible for Alexios and David with the support of the Georgians, to become the leaders of the byzantine resistance in Asia instead of the Laskaris and Vatatzes before proceeding with the recovery of Europe. Would this alternate “nicean” empire benefit from the rule of a legitimate imperial dynasty (possibly avoiding the usurpation of Michael VIII) and the addition of Pontus to its control?
