Your stack is way too weak compared to the garrison, and there's really no good way to take it down with your current options. The Sage sucks for combat and really shouldn't be used as anything other than adding casting skill at your Fortress. The wall is a huge bonus (+3 shields), and with Klackon's extremely high defense plus Heavenly Light (Elite Klackon Halberdiers would have 12 effective shields here), Shadow Demons certainly won't accomplish anything. Fire Giants' ranged attack will similarly do little, and they can't break through the gate easily. If you don't have Chimeras to rush in, it's basically hopeless.
Your Casting Skill is also too low to provide sufficient support. I would say that attacking this Fortress is just a waste of time, considering your Power and Gold income right now. Definitely focus on expanding...you should have at least triple your casting skill in Power and Gold income at all times, and usually more than that.
