Spa Resort Nazarick (Event)

Spa Resort Nazarick is a game event in Mass for the Dead that was released on November 29, 2019 to December 9, 2019.

Background
Momonga enjoying a steam bath on the 9th Floor in Spa Resort Nazarick enjoys the time relaxing while being attended by Miyoshi, his bathing attendant. Momonga hopes to use some of the other facilities on the area, though sadly many of them were damaged due to the Rifts. He wonders if they should rebuild it and gets an idea that he should have his subordinates prioritize its reconstruction. With the facilities back up and running it will hopefully relieve the Floor Guardians' fatigue after dealing with the Nazarick's rebuilding, rampant Chaos Beasts and other issues they been dealing with since coming to the New World.

Later in the Round Table Room, Momonga puts his proposal to his Floor Guardians. They are receptive on the idea to help cope with all their tension. Though Demiurge makes a note that if they repair the baths and enjoy themselves, they will be vulnerable to a Chaos Beast attack as they will bathe without their equipment. Seeing his point Momonga and Demiurge come up with a plan to have a cohort of undead stand guard around Spa Resort Nazarick while the Floor Guardians and master will keep their equipment in the vicinity just in case. Momonga uncomfortable of the idea of undead standing guard while he bathes, makes a suggestion in using golems, as they are cheap and tireless and allow for customization.

Plans are made to install golems within bath area for additional security and as inconspicuous as possible. However as Albedo and Demiurge go over the plans with Momonga, they find that it may be difficult as many of the golems within the Great Tomb of Nazarick were destroyed during the transfer to the New World. Surprisingly one particular golem managed to survive unscathed much to Momonga's annoyance to its creator. Finding this unacceptable Albedo has authorized a band to search out materials or technologies in the New World that may help repair their constructs.

Incident
The search begins in E-Rantel where the protagonist meets Leinas Rockbruise and attempts to engage her in a conversation. Particularly in the topic of golems, in order to gauge the New World's level of sophistication, sadly she cannot reveal much as that matter is a state secret and not within her expertise. After the protagonist finishes his conversation with Leinas, he meets with his party member Slimeko. While their findings so far are disappointing they hear a commotion from a few fellow adventurers that a lizardman had attempted to enter the city seeking aid for his people due to the temperature of the his home rising, but was turned away by the city guards. While Slmeko doesn't think much of it, save for the protagonist, who thinks the cause of the temperature increase could indicate the possible existence of the World Item Caloric Stone, a substance that could be used to make weapons and golems.

Interested in the group decide to investigate, though by the time they reach the gates the guard tells them that demi-human was turned away but is located further down the road as he has not given up seeking. The lizardman has taken to sitting by the road, asking any adventurer his request but is treated with fear and hostility due to be a non-human. The two approach him and he notices them he asks them if they are adventurers and are interested in his story. The two confirm, and introduce themselves. The lizardman grateful for having some open minded people, introduces himself as Zaryusu Shasha, a Traveler of Green Claw from the area between the Great Forest of Tob and the Azerlisia Mountains in the vicinity of the Great Lake. He briefly explains that his people live in their in peace, subsisting the fish in the waters. However, the water temperature of the lake suddenly began to rise for awhile. It was only a slight change, but grew warmer from the north side of the lake. Eventually the temperature rose and began to affect the local fauna in the area resulting in some insects and fish no longer being able to survive in the water and the fish that depend on them for food are also dying of hunger. Sooner or later this will affect the lizardmen. Since the phenomena that caused the Rift are still unknown to the lizardmen, Zaryusu sought the aid of humans as they have more knowledge on it. Sadly his people refuse to accept help from humanity despite the dire consequences hence why he came alone. Zaryusu asks the two if they will help him for which the protagonist asks the demi-human to wait as he contacts Momonga.

Momonga ecstatic that Caloric Stone may be in the New World. Albedo is cautions for being too hopefully, though the Overlord states that in the past Ainz Ooal Gown had once collected one of the Prismatic Ores and under certain conditions was transformed in Caloric Stone and benefited from it many uses. Even if it's just a rumor Nazarick must lay a claim on this resource before another takes it.

The trio manage to catch up to him, and find him being attacked by bandits.
