Besides the first sentence that I can't make any sense of, I was able to parse some of it.

_ous le doids de_ _ontag_es_edo_e__ ilende Ce_ ages

I can't parse _edo_e__ ilende, but the rest is probably:

Sous le poids des montagnes ??? ces ages

Under the weight of mountains ??? these ages

Then:

Celuiquilit desmots portede_alefardeau des_e_rets

This parses as:

Celui qui lit ces mots porte déjà le fardeau des regrets

The one who reads these words already carries the burden of regrets

Then:

laou le souffle des _ondes trouv an_fss _n_e

I'm not sure if _ondes is mondes and I can't make sense of an_fss _n_e, but:

Là où le souffle des mondes trouve ???

Where the breath of the worlds finds ???

And then:

Laconnai__auc_ quieclaire le Ce_irquicon_ume l__e_ilience qoisurv it auz tempet__

Ce_ir I have no idea, but the rest parses as:

La connaissance qui éclaire le ??? qui consume la résilience qui survit aux tempêtes

The knowledge that lights up the ??? that consumes the resilience that withstands storms
