The completion of Campaign Chapter 4 (so, Week 2 of the 11.2 patch) is required to access the "Ecological Succession" activities, where we build a functioning ecosystem in the Oasis biodome in the northeastern part of K'aresh.

When we complete the first [storyline=5693] storyline for the Oasis, we get access to general Weekly Quests, species-related Semi-Weekly Quests, and a Weekly WQ Ecological Succession where we fill a bar with the mentioned quests and other activities. When the bar is filled, the Weekly WQ auto-completes and rewards the [item=245611], and from what I saw, our first cache of the week always has one of 12 pets listed with this source OR this [item=242734] mount, and it seems to take the slot of a pet when it drops, so make sure you learn the mount immediately to not accidentally get mount duplicates while missing pets.
