I have this pinned to on-topic but it's mostly getting trolled on:

Can anyone think or find a reason for these to be important:

0x55dfxa
0x55dfxb
0x55dfxc
0x55dfx4
0x55dfx5
0x55dfx9
0x55dfx10
0x55dfx12
0x55dfx13
0x55dfx14
0x55dfx15
0x55dfx20
0x55dfx21
0x55dfx22
0x55dfx23
0x55dfx1a

1. They're Hexatrigesimal aka Base36
2. They're the non-hexadecimal variables from Sombra's (hilarious) xss-payload.js: http://us.battle.net/forums/static/js/vendor/injected/xss-payload.js
3. The 0x55 indicates high or low endian byte values  (http://teaching.idallen.com/cst8281/10w/notes/110_byte_order_endian.html). **This might play a role later on, hinting that we need to byte-swap in order to find the correct answer to something** (aka the bitchiness of unicode http://www.joelonsoftware.com/articles/Unicode.html)

I kind of feel that it might help with the image since it was in the same clue :S
