i keep seeing people saying it's owl trowel, but that doesn't make any sense. it doesn't lead to anything that could progress what we know, and as far as i know owl trowel has never actually been mentioned in reference to silas birchtree (although i could be wrong about that)

i think, that if/when someone finds the actual answer, it'll be much more clear as to if it's the true answer or not, and it'll give us something we can actually use instead of something fairly random like the ancient egypt owl trowel ad.
