Help I am not able to progress the main scenario quest...

I am stuck with no main quests after completing "Power of Deduction" quest... someone told me that the next quest is level 30 "wrath of the titan" and told me to go see commander r'ashaht rhiki at maelstrom command in limsa, but I went to talk to him but he doesn't give me anything..! please help me
(Also why can't i reply to a thread? I have to repost a new thread because of this inconvenience...)
p.s. My character is lvl 30 lancer and 15 marauder i already acquired dragoon job

It looks like http://ffxiv.gamerescape.com/wiki/Se...the_White_Lily is the next quest after http://ffxiv.gamerescape.com/wiki/Power_of_Deduction
