With a bit of imagination you can make this into a winter scene. That might be a snowflake in the middle (not a spider’s web), and to the right is a chimney with smoke coming out of it. Some footsteps in the snow down at the right?
In the little triangle at the left is the letter “e”, which works well with the other three disks:
F T1:1/4 i T1:2/4 r T1:3/4 e T1:4/4
So that’s the first ‘level 2’ clue: “Fire”.
Next I’m going to try and decode the strange symbols around the edges of all these disks…
