Ok, here's what happened: I summoned it in Ishgard for the first time in the Jewelled Crozier using a macro. Right behind my character I see the chat bubble pop up as the Garuda is summoned. Maybe I was seeing things, but I swear I saw it. I'm helping an FC mate craft one of these soon, I'll ask her to keep an eye on her newly summoned minion. If she gets a screenie I'll post it here. xD
