Notes:

The first time you talk to Infiltrator Tesara and follow the dialog, you are told to seek out Therin the Ancient and Alchemist Vaskerin, Therin kicks off the progression tasks and Vaskerin the major task for dealing with the Thel Ereth Ril. All you need to do is approach both npc's to complete the task. Once done, when you say "task" to Tesara you are offered a random one of the following 24 shared tasks:

These tasks each have a limited duration of 3 hours, reward a number of droplets, and have lockouts of 2 hours each. As I learn how much each task yields, I'll add that to the task name.
