There were 3 codes found in the A Certain Glyph Sequence blog post on the Investigation Blog.

[1] f172419i1907142006071912j01c04
[2] v8u4neewos9wku2
[3] 1lha1kkzxiu1j1i

Code #1

Observations

Event though the code is very long, it has a familiar format to it.

Code #2 and #3

Observations

Both codes have the same length and trying multiple different ciphers on each individually came to no results.
Recently they liked having two codes relate to each other for a solve.
