AncientWisemon (NPC)
One of the digimon that inhabit Grey Lord's Manor will put us to the test to advance to the next area, but who knows if he's lying or not...
Quest
Statue Room
On the right room after you enter the Manor you will find this knowledgeable digimon under service of the current Lord. He will ask you to identify which statue allows you to continue:
Should you require it, he even offers a tip in exchange of a riddle..."What is something that you can easily hold in your right hand, but you cannot possibly hold in your left?"
Should you fail on his tests... he would send you to the dungeons, to face Devimon(NPC).
What the Lord likes...
Once you reach the Library from the Grey Manor, you will find him acting as the librarian.
He will give you a riddle, like everybody else, and demand you to give him the book that his master sought most if you want to advance to the next area.
He will tell you that his master "Loves to read, and hates to write"...
so go find some books and give him what his master really wants!
