Query: Combinatorics arising from lax colimits of posets   In this paper we study maximal chains in certain lattices constructed from
powers of chains by iterated lax colimits in the $2$-category of posets. Such a
study is motivated by the fact that in lower dimensions, we get some familiar
combinatorial objects such as Dyck paths and Kreweras walks.
