At What Age Did Bob Went Missing

I need a little bit of help here regarding what exactly is the age of bob when he disseapered. Would apprecitiate if anyone can help explain or correct my misunderstanding.

So it begins like this, I am writing a fanfic stroy for wynncraft when I came across this problem.

From Ragni's discovery lore
One of two great fortresses in Wynn. Ragni has survived over 1000 years of war - sometimes barely. It is the hometown of the 146 year old hero Bob, who hasn't been seen in 16 years.

So from what I am reading, it means Bob dissapears only 16 years before 1000AP, where I assume is wwhen the player starts his journey. Making his year of dissaperance at his age of 130.

From Wynn's ultimate discovery (spolier alert)
By 886 AP, years of attack left Ragni on its knees.
Bak'al, leader of the corrupt, lead one final attack on the fort to finish it.
However, a hero fresh from his training around the province returned.
...
Bob has been missing since 984AP.

Now this all makes sense. Considering from Ragni's library. Bob was age 12 when he first went to train to be assassin. 5 years later, age 17, he mastered the ways of the assassin. So after 15 more years of training from the other masters. Bob technically finished his training at age 32.

At age 32, he bid farwell to his masters and returned to Ragni. (Chpater X). Here I assume it was also how it matches in the ultimate discovery. That Bob, was the hero fresh from his training around the province returned. So in the age of 32, in the year 886AP, he fought Bak'al (like in the cutsence).

So subtracting his 32 year old of age from 886AP, we can get that he is most likely born in 854AP. When I add 130 years, as previously mentioned (Bob dissapears only 16 years before 1000AP, where I assume is wwhen the player starts his journey. Making his year of dissaperance at his age of 130.) the time to 854AP, and in fact Bob is 130 years old when he was not seen in Ragni, 16 years before the player comes to Ragni.

However, in the same library, chapter XI, it states that 'For after the events of Ragni's 56th horde, some 40 years down the line at the ripe old age of 72, Bob vanished.' Coincidence is that, if the first battle where Bob fought Bak'al is when Bob is 32 as I calculated, 40 years later, at the age of 72, he disappears. Making him disapper at (886+40) 926AP...
So what went wrong? Please help. I am stuck at this question, and I can't really progress my story forward.

Any moderator can help? That would be the best since they know the story much in depht and better than stupid and youmg person like me.

 

The library is older than the discoveries. The discoveries are correct.

 

Wow thx so much ! I never knew that . I thought since the libraries are a discovery, they would not conflict each other.

So at the age of 130 instead of 72, Bob went missing.

 

Bob ain't missin' dude, he's just been playing a really long game of hide and seek but no one has been able to find him yet.
He is currently the record holder for universe's best hider.

 

Lol, he hid himself so well that he became a myth

 

He got a Nat 20 on stealth.
