Here is the relevant part of the script for nameless quest from eathena (ignore the line numbers and dots, my text editor adds those)
Code:
1794 nameless_n,169,254,0.?? script. #Aru_Trigger3.??-1,3,3,{
1795 .?? end;
1796
1797 OnTouch:
1798 .?? if(aru_monas == 20) {
1799 .?? .?? hideoffnpc "Larjes#Aru3";
1800 .?? .?? mes "[" +strcharinfo(0)+ "]";
1801 .?? .?? mes "What the hell...!?";
1802 .?? .?? next;
1803 .?? .?? mes "[Larjes]";
1804 .?? .?? mes "So... This is the";
1805 .?? .?? mes "island's true nature.";
1806 .?? .?? next;
1807 .?? .?? mes "[Larjes]";
1808 .?? .?? mes "Someone like me won't";
1809 .?? .?? mes "survive long in a place";
1810 .?? .?? mes "like this. I'm going to wait";
1811 .?? .?? mes "for you in the boat. Learn";
1812 .?? .?? mes "what you need to learn, and";
1813 .?? .?? mes "then come back safe, "+strcharinfo(0)+".";
1814 .?? .?? close2;
1815 .?? .?? set aru_monas,21;
1816 .?? .?? hideonnpc "Larjes#Aru3";
1817 .?? .?? end;
1818 .?? }
1819 .?? end;
1820 }
I you don't know enough about scripting to decipher it here is what it does:
If you walk on the coordinates 169,254 on the map nameless_n it checks if you are at part 20 of the quest (internal numbering, not used in any quest guides or anything like that) and you are it triggers the dialog. After you press the close button of the dialog it sets you to part 21 of the quest (which is the part where you get the books). If you DCed before you could press the close button of the dialog that means you're still at part 20, and need to walk on those coordinates to trigger the dialog again so you can proceed.
nameless_n is the night map, so if you go to 169,254 on the night map it should trigger the dialog and allow you to proceed. I'm guessing that those are the coordinates you end up on when you exit the warp of the house. Its probably a bug in the quest, if you go to the map before you're set as being as part 21 it should warp you to inside the house, not to the night map.
Good luck.
