Ok then...it seems that pellets work on DI. I don't have the patience to wait or to fiddle them to work. Maybe you guys have more patience than I have.
So you need to bake them in order to see the fireplace "TPoTS" code. Yeah because yesterday, I tried the "enlightment" process in The Watcher's then worked my way into the Path of the Shell and got linked inside Myst Fireplace.
In the fireplace, you have 4 choices:
1) to escape : open the door & exit to grab the sparkly (in December if I'm right) & the clothing item from Catherine
2) for a goodie
: enter the code known from the original Myst game
3) for a yuckie instead
: enter the code for the recipe of D'ni Eggs
4)most importantly to reach D'ni-K'veer : enter the code of TPoTS, the small creature-like code
For that 3rd code, you need the part shown inside the Lower Cave for that as the code parts are all scattered in "TPoTS" ages.
See how this way of playing URU is hard to get acustomized to? I said in my previous post to not bother much about the 4 glyphs (MOUL's TPoTS)...and then later in the same post to avoid making references to MOUL, I just fell in my own trap there.
Anyway... you got the main point: URU in DI is a strange creature (mostly because of its multiplayer environment I should mention because the equivalent offline (when URU is drizzled) is less strange but still...)
