Using the Galaxy map, travel to Silean Nebula and to Phontes System.
Your target is a very small planet, named Oltan, near Planet Dekuuna.
Scan Oltan, and after you find the Elcor Flotilla, return to the Citadel.
Talk to the ambassador to complete Dekuuna: Elcor Extraction.
NOTE: If you saved the civilians from Dekuuna before talking to the Elcor Ambassador, then you will have to exit the Embassies area, and return to him, to finish the quest.
