Go with the Harmony option and build the Xenodrome wonder which gives a free Xenosanctuary needed to complete the quest.
I dont think you need Xenomass for the free building from the wonder right?
Actually I think yo can build the Xenosancturay without Xenomass in the capital, it just consumes 1 from your resource pool.
