Alexios wrote to Kilic Arslan, warning that Chaka was a bigger threat to him than to the Byzantines

Summary:
Chaka was too belligerent to be long quiet, but soon re-established himself at Smyrna and again built raiding vessels and warships of all kinds, retaining the same purpose as before. In the face of this hostility, Alexios appointed Konstantinos Dalassenos as his chief admiral and sent him out, but also wrote to Kilic Arslan I to enlist his aid. His letter warned that Chaka (who called himself emperor) probably hoped to dominate the Muslim world, not Byzantium; he was too experienced to expect that. Alexios suggested that the sultan should discipline Chaka, by force if necessary, just as Alexios was trying to exclude him from Byzantine lands
