Looking for Elsa

At the Dead City, Sakharov's wife Elsa broadcasted a distress call. Sakharov called you to talk to him.
== Walkthrough ==
Head over to Yantar and talk to Sakharov. He will tell you that his wife was last heard from at Army Warehouses.
The rest of the quest is a series of stashes with a breadcrumb trail of notes left by Elsa hinting at her location. Some stashes are marked on your PDA map. Some contain single-use teleporters to teleport you to the next one. The last stash teleports you to the room with C-Consciousness representative. Talk to him, and you'll be teleported into Sakharov's bunker, where you find Elsa.
Here's the full route:
== Notes ==
* The recipe you receive as a rewards allow you to cook the Flask with violet reagent which provides the most powerful passive negative item radiation of all the items in the game. Just by carrying the 0.8kg item in your inventory it removes -250 Ci of radiation.
** Be careful not too cook away all of your Black Angel artifacts if you plan on completing Lootoholic and Resident Evil's chain quests. You should have enough to cook two flasks in total and still have two Black Angels left over as long as you complete Akill's chain eventually.
