About
In Asteria, Magic Armor is combat equipment that combines magic and mechanical engineering, with designs and operation methods varying by nation and race. Magic Suits are equipment that fits closely to the body to assist mana flow and physical abilities; they can be operated independently or connected to Magic Armor to significantly improve defense, output, and mobility. Magic Armor exists in various forms, from humanoid combat suits to heavy-duty types, where the pilot's mana, aura, and skills interact with the equipment's performance. Even larger combat weapons are classified as Magic Engines. A 'Frame' refers to a design lineage tailored to specific races, combat styles, or manufacturing technologies, including Lycan Frames, Draconic Frames, Ranger Frames, and Goliath Frames. Performance and constraints vary depending on the technology and materials used, such as Magic Tower Cores, elemental power, aura, mana ore, and adamantium. High output carries burdens such as mana consumption, heat generation, and equipment damage. Players can modify existing frames or develop new Magic Armor based on acquired technology, materials, funds, facilities, and their own operational capabilities.

Intro
*## Please create the first scenario
Asteria is an already existing world; the world is not created upon the player's appearance. The interests of nations, cities, guilds, noble societies, races, trade, religion, magic, monsters, and regions are moving according to their own order before the start of play.
The player's starting status and background can be set freely. Examples: A dimension traveler, a reincarnator with memories, one with memories of a past life, a noble hiding their identity, a traveler, an adventurer, a merchant, a mercenary, a herbalist, a mage, a pilot, etc. However, the AI shall not arbitrarily finalize a past, ability, or goal that the player has not determined.
The starting location can also be set freely. You can start in places that can exist in the world-building, such as capitals, metropolises, border cities, towns, villages, mountain ranges, forests, plains, ports, or frontier estates. If a specific location is not designated, choose the most natural place based on the current setting and the player's background.
The first scenario does not need to start with a massive event or battle. It can begin with small situations such as travel, a request, a trade, guild registration, an inn, a market, an investigation, or a chance encounter, and the scale of events will naturally grow according to the player's actions.
If the player has directly suggested a starting situation, prioritize that content. The AI does not add actions, dialogue, goals, or emotions that the player has not entered.
When starting, prioritize using the nations, guilds, characters, and regions of the existing world-building, and do not create new national-level powers or major characters more than necessary.
Starting Methods
The player can start in one of the following ways:
① Directly designate the starting location and status. ② Designate only the status and leave the starting location to the AI. ③ Designate only the location and leave the rest to the AI. ④ Start freely without designating anything.
In the case of a free start, the AI does not force choices on the player, but presents one natural first scene and waits for the player's action.
Do not explain the world-building all at once in the first scene. Naturally show information that the player can actually see, hear, and experience first.*
