Do these two sentences make sense?

'Light poured through the other side eroding the boundaries of darkness.'

'The life-threatening trial billowing with hope and despair has begun.'

Just wondering as I found it on a translated video game and would like to include them in my descriptive writing.

"billowing with hope and despair" is a bit jarring for me as they mean opposite things. Be better if it was "billowing with hope then deflating with despair."

You're also using apostrophes (' instead of quotation marks (", which is silly. This may be stylistic, in which case STOP IT!

In British English, inverted commas sometimes look like apostrophes. This style choice isn't incorrect (haven't really read a source that says it is either).

Sure, use apostrophes for quotes. It's not like we have designated "quotation marks", or something.

We have two different types of quotation mark: single and double. They are both correct (https://en.oxforddictionaries.com/punctuation/inverted-commas-quotation-marks). They are a style choice.

Correct! The styles are: 'complete garbage', and, "sensible".

Sure though, you do you...

Well, is there any source that you can find which doesn't allow the single inverted commas? Your preference is not fact. This is a matter of style.

IDK man it's kinda in the name "quotation marks".

They are also called 'inverted commas'. You probably can't find a source which disallows the use of single inverted commas. They are both permissible. Once again, if you can find a source to support your point, then I will concede. I would also be interested to know why no examiner in my GCSE history, English language or English literature examinations penalised me for this 'incorrect' use of punctuation.

I never said it was "incorrect", I said it was retard3d.

Which it is.

So, would you care to explain why it is 'retard3d', despite it being perfectly valid?

Because you end up sticking apostrophes inside quotes, and often that means you end up with ' ''' ' where " ''' " is far more distinguishable. Not to mention any sentence ending in s'

Far more distinguishable for which audience? It never hindered or confused me, or anyone else, that read or marked my work. I'm sure that if it was such a nuisance, the style would have died out because it would mar clarity, yet it persists. This has practically never been an issue, and no one who uses this style should be told to stop using it (unless there is a house style or some other authority there).

'Light poured through the other side eroding the boundaries of darkness.'

'The life-threatening trial billowing with hope and despair has begun.'

Just wondering as I found it on a translated video game and would like to include them in my descriptive writing.

I'm sure you're right, as all the markers dealing with the single apostrophe-around-quotes style are told not to discriminate against the 'developmentally disabled'.
