It's definitely an 'F'. Compare with the 'F' in the "PREPARE FOR GLOWBES" message.

Never mind any hints from me; my guess was obviously wrong. I was thinking of something like "TRIBAL" + "GH ISND" would rearrange to "BRIGHT ISLAND", where the Glowbes might come from.

If the message "TRIBAL F" + stuff is an anagram for Something Island, we've got T, R, B, and F left over, and still need S, N, and D.
