Because the nobility knows 99% of the adventurers will die. Best-case scenario, the adventurers recover a long-lost treasure or defeat an ancient evil threatening the kingdom, and the nobility loses some of its cash.

It's like a human lottery.

Because by tying the adventurers to their nobility they ensure
1) they stick around to help out. No one is going off to raid a jungle temple if the orcs are busy raiding the estates back home
2) They become aligned with the nobles within the country rather than with the church, the city dwelling bourgeois, or god forbid a different country
3) These adventurers invest in local infrastructure to try to improve their land or standings. Feasts, mighty castles, ultra fancy clothes, these all cost money and in most cases that money will flow into local coffers rather than distant foreign lands

Combine these two and, in a nutshell, you get the most competent of the adventurers as defenders of your realm and, being used to a lifestyle of spending what you have while you have it since you may die soon, more likely to spend in your holdings.

A better life for your children and your family stretching forever onward is also a stronger incentive than a pile of cash that a man with a fast sword could more easily earn through banditry.

if you don't elevate new nobility, the ones you got wind up inbred.

>honorary

Assuming this happened (which it doesn't) a hereditary honorary title would give you a man who owes you his position but needs your money to keep up the requirements of such a title. So you get a pet problem solver.

In reality most people who get knighted or better for their great deeds get the land to go along with it.

>>43640974
Except that noble titles were often granted in this way to people who did some great service. Historically. The titles become hereditary afterward, but you can create new ones out of whole cloth if you're the king. If it's the sort of title that comes with land, often it'll get carved out of the fief of the rebellious upstart you helped kill to get where you were today, your own property will get promoted to the status, or some lord who's accumulated a load of lesser titles (as happens often in a hereditary system that demands marriage within itself) will give it to you in exchange for your support as part of their bid to sponsor you for the position.

You ever heard of somebody being "created Baron of such-and-such"? That's what this was. It's a political institution. Of course it was going to be used politically.

>Why is this allowed?

People believe noble blood literally makes you better. They also believe the converse, that if you're capable of pulling off a series of legendary actions, the blood pumping in your veins must be worthy of a noble title. And if your children inherit your noble blood, why shouldn't they also inherit your title?

>why shouldn't they also inherit your title?

I'd feel a little weird calling Reggie "the Defenestrator of Wizards" for something his great-grandfather did.

If you're talking about a feudal system then this is very normal.

People were granted titles, land and labour by the king because of some deed. The better question is. If you saved an entire town from orcs then why shouldn't you get land and a title?

>>43640974
A title is attached to land or better yet the owner of a piece of land gets the title. Since kids inherit land they inherit the title that goes with it.

>>43642395
By title they mean "Lord/Lady X of Place" or some such as opposed to "XYZ the destroyer".

Unless you were just joking, in which case I apologize.

>>43641422
I considered this to be the case in my setting.

Then the new generation is born into power instead of acquiring it, and are as classic noble as possible.
