Title: 2-filteredness and the point of every Galois topos

A locally connected topos is a Galois topos if the Galois objects
generate the topos. We show that the full subcategory of Galois objects in
any connected locally connected topos is an inversely 2-filtered
2-category, and as an application of the construction of 2-filtered
bi-limits of topoi, we show that every Galois topos has a point.

NOTE: in definition 1.2 iii) "Z" is supposed to be locally constant.
