The Deer Clan originate from an honored Otomo, not a Daidoji. Their founder was Otomo Shika, who was a renowned Imperial Matchmaker. She was given leave to form the Deer Clan, as an 'honor' for her own relationship, which was a marriage of love, in stark contrast to her practices. She married a rakish ronin warrior.

This is a higher fantasy of Rokugan. The Supernatural/Spirits are more active and present than standard L5R.

Even without a spiritual sixth sense, every day people can see spirits. Think Princess Mononoke level here.

Sixth Sense takes it to 11.

Momoku acts as normal.
