It's so majestic that it's a shame to keep it just for the Loremaster: I would like to show it to the players once their Heroes reach it.
Did the artist (Jon?) publish somewhere the picture sans the diamonds with the numbers? I can somehow obfuscate the tunnels, but the diamonds are too big for my (abysmal) painting skills

Btw, I'm asking because Jon put some maps on deviantart sans diamonds in the past (Dol Guldur, Rivendell, etc).
