Danac

Danac (ダナク) is the main settlement of the 59th Floor of Aincrad.

Description
In the Light Novel, the town of Danac is not described other than the grassy hill Kirito and Asuna nap upon.

The anime depicts Danac as a rather large town with outskirts, and dotted with windmills. The city’s Teleport Gate seems to be located in between the city’s “downtown” and outskirts.

A Murder Case in the Area
Asuna finds Kirito napping and scolds him for not clearing or mapping the nearby Dungeon. Kirito argues that this particular weather setting is complimentary, and that Asuna would understand if Asuna were to rest beside him. She promptly falls asleep, and Kirito watches over her in case someone were to Sleep PK her.

About 8 hours later, Asuna wakes up. After feeling dumbfounded, Asuna begins to attack Kirito but ultimately stops herself. She intends to repay Kirito by buying him any requested meal. The duo then leaves for Marten.
