So I've got another question, this time regarding the big crystal. Suppose a character were to climb or fly up to the big crystal. Would they experience any effects from being near it? Would they be able to touch the crystal?

Edit: Never mind! I actually did find the answer to these questions somewhere back on age 5 (plus some interesting defense mechanisms and hollow vibes details.) I will say that I'm curious to know whether or not it's possible to 'communicate' with the big crystal somehow.
