Magitek Objective Question

[Raldo]

There is a FATE in the Peaks where a big magitek spider spawns, and the objective is to kill it before it reaches its destination. The magitek spider's target destination is marked as "Magitek Objective" on the map, just so you know where it's going to go and how much distance there is left. Once it reaches that destination, it shoots missiles up that come back down to destroy itself, ending the FATE in failure. I'm very confused, from a lore perspective, what the purpose of this FATE is supposed to be (but I don't remember what the FATE's description is -- maybe it's explained there). It seems like a giant waste of Garlean resources.

tl;dr It's a spot where a FATE ends, if you don't kill the FATE boss before it reaches that spot.
