1 - Azlan in Chains
The first Typhon Log is at the start of the map on top of a small building.
2 - Azlan's Escape
There are two paths leading to this sewer-like room. One is broken and the other one not...
3 - Azlan's Betrayal
The third is in The Yard. There is an overgrown bridge / walkway on top of a building.
Climb the building to get on the walkway.
Then use the piled boxes to get on top.
You can jump up while looking at the overhanging plants. It will work.
