R > kRO's Guild Storage NPC

[Ragno 57]

According to kRO 2014.02.01 Notice it was added a Guild Storage NPC in every city:
 
 

- 길드 창고 NPC가 각 마을에 추가 배치됩니다.
　→ 모로크, 움발라, 코모도, 이즈루드, 알베르타, 니플헤임, 라헬, 베인스
　　 휘겔, 리히타르젠, 아인브로크, 아인베흐, 유노, 루티에, 브라질리스, 쿤룬
　　 모스코비아, 용지성, 아요타야, 데와타, 포트 말라야, 아마쯔
 
 
- Add a Guild Storage NPC that will be placed in each village.
　→ Morroc, Umbala, Comodo, Izlude, Alberta, Nifflheim, Rachel, Veins,
　　 Hugel, Lighthalzen, Einbroch, Einbech, Yuno, Lutie, Brasilis, Gonryun,
　　 Moscovia, Louyang, Ayothaya, Dewata, Port Malaya, Amatsu.

 
I have this questions about this update:

• How does this npc works? Is it an independent npc or it was added via Kafra Employee?
• Can every guild member access the guild storage? Or only those who has the storage check in guild window?
• What are the requisits to use it?

And also want to request for somebody with kRO account to please bring screenshots (or video if possible) with the official dialogues of this npc to make it a script.
 
Thanks!
