Chapter 8: OCC
So just a quick recap of what you know and your current situation, and from there tell me what the PCs are going to strive for next:
1) Yuu's parents are under house arrest. They seem well. The exact reason of their forced isolation is unknown, but the perpetrating party is likely members of the Reforger faction within the Ossylian government. This is the more militant-minded, hawkish of the three factions. Given the Jin family history within the military it's slightly odd that they would take actions against them.
2) Ossylia is still under martial law, with curfews and blockades with ID checks in certain areas. Immigration control is heightened still following the brief period of isolation. The exact reason for all the enhanced security is unknown, but could be related to the Chlornetherium explosion the PCs are well aware of.
3) Yuu's friend and former classmate, Saya, is a Lieutenant in the Ossylian forces and is currently assigned to border protection within the capital, read Immigration control. She's volunteered to inquire after any reports of missing chlornetherium shipments, or any expected large incoming shipments, pursuant #2 above.
4) The status of Lasrane is unknown, but it is likely he is either captured by the local Chapter of the Order of Ashes, or dead. In any case the local Chapter is aware that someone was involved in Lasrane in some capacity and had been monitoring the meeting point the PCs designated when they handed him to a hospital before fleeing the capital. After an attempt to meet Lasrane the PCs spied upon Order agents who were staking out the place through a third party. It is likely the local Chapter is aware that Zelpuz had encountered or become involved with Lasrane in some capacity, making his status in the city uncertain at best and dangerous at worst.
5) Outside of Ossylia Myria went on to Arghos to report directly to the Order HQ from there. Yuu's family in Hasheli, a local governor, is fine and has largely been kept in the dark as to any political machinations in the capital; whatever is happening has been largely contained within the city is seems.
